AQ top pair gets donked into

[FlushTheToilet]

Villian is unkownn, 26/4/5 over only 20 hands. We've not played a real pot together yet, and I haven't seen him do anything noteworthy.

Titan Poker 0.50/1.00, hand converted by the iPoker Converter at Talking-Poker

Button ($159.80)
SB ($104.00)
BB BB ($94.40)</font>
UTG Hero ($226.18)</font>
UTG+1 ($114.25)

Preflop: Hero is UTG with A Q
Hero raises to 3.50, 3 folds, BB calls 2.50.

Flop (7.50) 7 A T
BB bets 4.00, Hero calls 4.00.

Turn (15.50) 6
BB bets 5.00, Hero calls 5.00.

River (25.50) K
BB checks, Hero bets...?

Should I raise the flop or turn here, or wait for a better read before trying to punish weaker hands? The only real draw, the OESD came in on the turn.

Value bet on the end with TPTK? How much?
